What you’ll need
You don't need to be a developer to set up this integration. Follow this simple guide to get started:
- A PostGrid account
- A Relevance AI account with access to your projects and datasets
- Authorization credentials (you'll connect securely using API keys—no sensitive info stored manually)
Security & Reliability
The PostGrid integration utilizes secure API authentication, ensuring that only authorized workflows can access your print and mail services. Relevance AI manages API operations (such as verifying addresses, creating contacts, and sending letters) seamlessly in the background—eliminating concerns about errors, formatting, or limitations.
With built-in address validation and standardization, your workflows will operate efficiently, ensuring accurate delivery and streamlined contact management, even when dealing with varying address formats.
No training on your data
Your data remains private and is never utilized for model training purposes.
Security first
We never store anything we don’t need to. The inputs or outputs of your tools are never stored.

To get the most out of the PostGrid + Relevance AI integration without writing code:
- Verify addresses before use: Always validate addresses to ensure accuracy and reduce delivery issues.
- Utilize standardized formats: Use consistent country codes and include postal/ZIP codes for better address verification.
- Start with small batches: Test mail processing with a limited number of letters or contacts to identify potential issues early.
- Monitor delivery status: Keep track of mail delivery to ensure successful dispatch and address any failures promptly.
- Implement error handling: Use try-catch blocks to manage API errors gracefully and log issues for troubleshooting.
